Manual boost controller

[Ben hdi306]

Just fitted a manual boost controller went around the block and its boosting to 18 psi :/ it's a spring and ball one I got the link off a thread on the forums the spring is not compressed at all but the boost controller dose have a little hole in the back of it dose that matter?

Btw my car has a fmic but has not been remapped yet.

Well what was it boosting before?

[Poodle]

14psi.

Maybe it's got a stiff spring which requires 18psi min to compress. Perhaps get a softer spring or get it mapped!

Stage 2 remapp at the weekend just don't wont to cause the engine to go bang or damage do you think it will be ok or not?

[Just Sean]

be fine. dont go over 25psi!

[Ben hdi306]

But it's standard 90 bhp lol

[Mr Whippy]

A stage 2 remap with no other changes will hit around 18-19psi due to exhaust energy, so just be sure when the remap goes on to be gentle and check the boost doesn't fly up!

Assuming you have FMIC on now then the boost itself won't be bad, but it must be leaking a fair old bit off from the boost controller to hit 18psi on 90bhp mapping.

Boost controller has a hole in it to leak air. Are you sure you have it wound the right way (ie, totally closed, not totally open?)

Cheers

The spring and ball are not compressed so shouldn't it be running 14psi like it was before I fitted it?

I know it has a slightly longer distance to travel but would that matter?
